Engine stalling
Stalling is the engine dying while idling or just as the car pulls away.
A lost crank signal (P0335), an idle-control fault (P0505), or a misfire (P0300) can all cut power without warning. Note if it happens only when coming to a stop.
Do not clear the code before you have saved it. The DTC page for that code lists the usual signal and idle checks.
A trouble code marks a condition to test. It does not by itself prove which part to replace.
